25' x 30' x 6" (1/2 foot) is 375 cubic feet.

divided by 27 is 13.88888 cubic yards, so order about 15 yards since you grades may not be exact. - Mkae sure you have sidewalk or something else poured so you have a place to put the excess. They usually do not like to take concrete back.

Neo, did you do that all by yourself? Or did you ask T's 9th grader for a formula? Just razzin'.

Revievl's right, 6" is half a foot (a foot is 12", so half that is, well .5). Easy mistake to make. Got a friend who uses a slide rule kinda thingie her concrete guy gave her... put in length x width x depth and you get the right order off the thing, but I like doing it the "hard" way.

For a 4" slab do length x width x (neo table). Divide by 27 than add some, round up, or add more if you're not sure of the grading. My concrete provider will take it back if I order too much, but they charge me for it 'cause it's junk if it's not used.

Long ago,
In a galaxy far far away.....
I was a field engineer,
i.e. building layout and
site work.
Dimensions and grades are all
in feet, 10ths, and 100ths.
Stuff is engraved in the
lizard brain. Handy when doing math
with measurements to the 8th!
